Food Allergy
Simply put, food allergies are caused by an abnormal immune response when food enters the body. Food allergy can be divided into allergic reactions caused by IgE immunoglobulin E, early-onset or acute caused by lymphocytes. Anaphylaxis, oral allergy syndrome, or urticaria, which can trigger eosinophilic esophagitis, gastritis, gastroenteritis, or atopic dermatitis (ie, eczema), and, in rare cases, non-IgE food allergies. Which are colitis, celiac disease or dermatitis herpetiformis.
Acute Allergic Reaction
Due to an acute allergic reaction to IgE immunoglobulin E, patients may develop urticaria, and may also experience symptoms such as abdominal pain, diarrhoea, vomiting, throat swelling, tracheal constriction, and sudden drop in blood pressure.
